Help with network...includes 2 switches

Hi All,

Having a bit of an issue with my network and wonder if peeps could help out please.

I have just purchased an additional giga switch to sit in the front room, I connect the TV, TV Box, & Powerline to this and all is fine...I then connect 2 cables which go into a double socket in the wall, this then goes into another switch in the loft which in turn powers 2 sockets in my new manroom/office...once these are connected the network goes down and no internet etc.

Nothing is currently connected in the man room as it is still needing to be decorated...

For whatever reason am I doing something wrong? The switches are all unmanaged, do I need to ensure the switches are connected to the same port numbers? I.e. Switch 1, port 2 musty be in port 2 in switch 2?

Hope this makes sense!

You've made a loop by plugging the switches into each other twice. Only plug in one cable.

Ahh OK, so plug one in and the switch in the loft will ensure both sockets in the man room are active?

Yes, but it sounds like the switch upstairs isn't really required. The two cables from downstairs could connect directly through to the two sockets upstairs.

As above, switching loop is happening. Don't worry, it's brought businesses down.

Businesses with bad network teams

The switch is there to supply other rooms upstairs if ever required in the future.

Bad enough not being able to get on to play BF1!

But for now it's just wasting electricity and potentially limiting available bandwidth (although this is unlikely to be an issue).

It'd be ok if you could configure the two connections in a trunk/bonded configuration, e.g. LACP, but your switches may not support that.
